sort it once to get the word prefixes in order. uniq -c to get you a
count of the prefix occurrences prepended to the prefix after removeing
dups, sort it again to put the prefixes in order by number of
occurences.
If you really were the geek you claim you were :-), you would have known
the two sorts are for different reasons and there's no way using this
approach to avoid both. However, wc may be useful here if properly
applied. Have to think.
and if you haven't rewritten sort on your box to be faster, what kind of
geek ARE you? :-)
